What is the difference between a reciprocal function and an inverse function?

A reciprocal function will flip the original function (reciprocal of 3/5 is 5/3). An inverse function will change the x's and y's of the original function (the inverse of x<4,y>8 is y<4, x>8). Whenever a function is reflected over the line y=x, the result is the inverse of that function. The y=x line starts at the origin (0,0) and has a positive slope of one. All an inverse does is flip the domain and range.


Find the value of x: 2(4x + 4) = (4x - 12)?

2(4x + 4) = (4x - 12) 8x + 8 = 4x - 12 8x - 4x + 8 = 4x - 4x - 12 4x + 8 = -12 4x + 8 - 8 = -12 - 8 4x = -20 4x/4 = -20/4 x = -5


What is 4x 8?

4x -8 = -4


What is 8 plus y equals 4x in standard form?

8 + y = 4x8 + y - 4x = 4x - 4x 8 + y - 4x = 0 8 - 4x + y = 0


How do you rewrite - 4x equals 2y - 16 so y is a function of x?

-4x=2y-16 +16 +16 (-4x+16)=(2y) /2 /2 y=-2x+8


Given the equation fx equals 2x2 plus 4x plus 8 what is the solution by solving with the quadratic formula?

It can't be solved because its discriminant is less than zero


How do you solve -4x plus 8 equals -4?

-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3


What is the solution of 4x-3-8 equals 8?

4x-3-8 = 8 4x = 8+8+3 4x = 19 x = 4 and 3/4


What is 8(4x- 12) =?

8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1


What is the inverse function of y equals 8x plus 5?

The inverse function is obtained by interchanging corresponding values of x and y and then transposing the resulting equation to make y the subject. f(x) = y = 8x + 5 therefore f-1(x) = x = 8y + 5 : 8y = x - 5 : y = (x - 5)/8 The inverse function of y = 8x + 5 is y = (x - 5)/8
